McKenna has joined the firm as a partner and co-chair of San Francisco-based Orrick’s Public Policy Group. San Francisco-based Orrick is one of the leading U.S. law firms representing technology, financial services, energy and consumer products companies.

“Upon deciding to return to private practice, I looked for a firm grounded in Washington State that offered a top-tier national and international platform and a client roster of leading technology and consumer product companies,” McKenna said in a statement. “Orrick offers all of that plus a truly innovative public policy practice.”

McKenna was an attorney at the law firm Perkins Coie before launching his political career in the mid 1990s.

At Orrick, Herrington & Sutcliffe, McKenna will work on privacy and data security issues, as well as regulatory compliance issues, with Orrick clients.

As attorney general, McKenna was active on tech issues, including his work on the passage of anti-spyware laws and laws to combat identity theft. He also was the first state Attorney General to build a computer forensics lab to collect evidence of Internet fraud.
